BALL-BEARING.

SPECIFICATION forming part of'Letters Patent No; 609,503, dated August 23, 1898.. Application filed May 11, 1898. "Serial No, 680,401. (No model.) 4

.To af/ZZV whom t may concern/.-

Be it known that I, IRA- FAUNCE, a citizen of-the United States, and a resident of Williamsville, in the^"countyof Sangamon and State of Illinois, have invented a new and use-'M ful Improvement in Ball-Bearing Axles and Hubs, ofwhich the following is a specifica- `of one ofthe series of balls.

'the balls are inserted and removed from their Vplaces in the hub and axle. 'Fig il is a posterior View of the outer plug, showing a locking device for holding it in place; and Fig..5

is a posterior view of its lugs.

Similar letters refer to similar parts throughout the several figures.

the inner plug, showing My invention consists of an axle A, having V- in itseveral annular grooves M M, semicircular in section, passing around-it in planes perpendicular to the central line of the axle,

a hub B, fitted over the axle A andWith several grooves N N in its inner surface, semicircular in section and corresponding with those in the axle A, so that hub B and axle A may. operate together, the grooves M and N in each series forming a perfect annular groove of circular section, aseries of balls C C of a size and number to fill the several se- 'ries of annular circular grooves made by the grooves M M and N N, a plug D, placed in the hub B, one for each series of balls and grooves, although only two are shown, made removable, so that the balls in each series may be inserted or removed easily, a plug E, turning into the hub B in a series of threads and Vhaving a locking device F at its outer surface,

the plug G, threaded into the hub, and small holes g g, leading from the pit in which plug G is placed to the series of grooves and'balls.

The hub B is slipped over the axle A, and the balls C C are placed in their proper places by removing the plugsE and D and inserting the balls till the annular circular groove has the requisite number within it. The plughDA is then set in place, the anterior end of which is cut semicircular to correspond with the V:part of the `hub removed'which the plug D replaces. There are two lugs O and P on the sides of plug D, near the posterior end, which iit closely into slots out in the hub B. The said lugs O and P hold the plug D firmly in place, so there can be no rotary movement of Lplug D and no interference with the movement of the balls C C in their respective grooves. The lugs O and P alsoA prevent plug `D from beingforced nearer the axle A than is proper by striking with their anterior ledges the ends of the slots into which they fit. The lugs O and P are made of different sizes to make it impossible to wrongly fit the plug D into position. Plug D has a small hook-lift in its posterior en-d by which it can be removed.

The plug-E is screwed into the hub B till its anterior endv lits tightly against the posterior` end of. plug D; and thus makes D1 assolid and firm as if it werea partof the hub B. Plug E has alock F in itsexposed end, which when in place rests flush with the surface of the hub B and plug E. Lock F moves on a pin fand is Aheld in its normal position. by a coil-spring s. The lockF also acts as a wrench by which the plug E may be removed.

, Each one of the series of circular grooves is provided with the means for removing and replacing the balls heretofore described; but

they are located on the hub so that no two of them will lie in the sameplane on the same side of the hub.

I provide for'oiling the balls and annular grooves through holes g g, passing from the annular grooves and balls to a pit inthe hub B, 4into the outer partof which the plug Gis screwed. Plug G is to be removed by an ordinary screw-driver.

Having thus described my invention, what I believe to be new, and desire to secure by Letters Patent, is-- In aball-bearing axle and hub, the combination with an axle A having several annular grooves in its surface, -the hub B with annular grooves on its inner surface corresponding with those in the axle, balls C C filling the raoeways formed by the grooves in the axle and hub, plug D With lugs O and P near its as a screw and holes g g, all substantially as posterior end and With its anterior end out and for the purposes set forth.

across With a Curved groove semiciroular in section, plug E having threads on its perme- IRA FAUNCE 5 ter, its anterior end tting firmly against plug D and in its posterior end a looking-arm F, pin j' and coil-'spring s, the plug G threaded In presence of-` R. L. RosEBRoUGH, ED. L. GRoVEs.
